Hi,

I understand that you wish to extract audio from the given text file.

You can use importdata function to read the file into an array and sound function to extract audio from it.

A=importdata (‘Sample.txt’); 
sound (A,8000); 

The file attached by you contains ‘[‘ and ‘]’ in the beginning and end. importdata would store the file as a single cell in this case. So, ensure that you have removed ‘[‘, ‘]’ and then save the file again.
